of (it orado, have invented certain new and I useful Improvements inCushion-Beating hlachines; and I do declare the following to Pat) full,clear and exact description of the invention, such as will enable othersskilled in the art-to which it appertains to make and use the same,reference being had .he accompanying; drawings, and to the characters ofreference marked thereon. which form a part of this specification.

My invention relates to im iiroveinents in .ushion beating; machines otthe class iin United States Letters Patent No. W5, dated May 'Zth, 1901.

My present construction, while of the general class of machines forth inthe said patent, contains a number of lHIPLOVBlDQDtS over the saidconstruction.

T will proceed to deseribe the invention in detail, reference being madeto the aceompan' 'ng drawino' in which is illustrated o I r 3 anembodiment there-oi".

flexible hose pipes connected with the fitting are broken away close tothe latter.

The same reference characters indicate the same parts in all the severalviews.

Letthe numeral 'designate a suitable framework composed of upright framebars the cit-y and county oi Denver and State 6, '7 and 8 onoppositesidesof themachine, these upright bars being connected" by topand bottom longitu(finally-disposed bars 9,-

10 and 11.. This framework may be of. any suitable construction; and.further detailed ex dunation is therefore unnecessary.

To the top of the machine is applied'a closed housing 12,'w hich coversthe'entire mechanisnrfrom above except such parts as must necessarilybee'sposedinorder to be accessible for applying power and deln'ering thenecessary air to the machine for operating purposes.

Journaled on thetrameworlr at the opposite ends thereof are't-wo shaftsl3 and 14.1; upon which are made fast two pairs of pulleys and 16, thepulleyslh being at the rear extremit ot' the machine, and'the pulleys 16at the forward end thereof. These pulleys carry two endless belts l7,suitably separated and connected by slats or transverse bars 18, thebelts and slats or bars constituting an'endless travel Yeyer, which isoperated from a lie not shown, with which is cor-12kt 19, which leads tou' pulley transverse shaft 21. journzf all the upper part of theframework. on this same shaft is a smaller -pulle from which leads abelt 23 to arelati 1y large pulley 2st fast on a shaft- 25 arr dtransversely of the machine and passir tween 'theftwo runs of theconveyor. On the opposite extremity of this shaft 25 is made fast a relatively small pulley 26, fromwvhich leads a belt 27 to a relatively largepulley 28, fast to the shaft 1%, journale'd in boxes "29 at the forwardend oi the machine, and-carrying the pulley 16 to which reference-hasalready been made, whereby a relatively-slow motion is transmitted tothe conveyer, the-speed of the line shaft being stepped dOYVIlfSO tospeak, for the purpose. w v

The shaft 13; upon which the pulleys 15 are mounted, as heretoforeexplained, is journaled in boxes 30, secured to the rear end of theframework. Fast on the shaft- 21 is a drum 31' carrying heaters 32,composed of 'straps,-whose inner extremities :are secured to the drum,as shown at '33,'by means of bars 34-, which are applied-to theextremities of the beater straps, suitable fastening devices beingpassed through t-he. said. bars andt-he beater straps, whereby both areseretired to the drum. The Outer":.GXtl'GlIlltlQS 35 of the beaterstraps are each composed of -a number of thicknesses of leather, wherebythese extremities are made relatively heavy,

thus facilitating the beating or dirt loosening'function. Each series orset of beater straps is arranged in staggered relation with reference tothe series of straps on each side thereof, whereby the said straps orwhippers act more advantageously upon the cushion which is passingthrough the machine. This beater is located a suitable distance abovethe conveyer to allow a cushion 36 to pass below'the beater, whiletraveling upon the upper run of the endless conveyer.

.The beater is inclosed by the housing 12, to the opposite sides ofwhich, below the beater, are secured, as shown at 37, the extremities ofleaf-springs 38, which extend. inwardly and forwardly from theirfastened extremities, the said springs lying in the path of the oppositeside edges of the cushion 36, as the latter is traveling through themachine, from rear to front. To these springs 38 are secured extensionwood members 39, which extend forward of the springs. To the forwardextremities of these wood members are secured elbowshaped metal conduits40, one extremity of each conduit entering a flexible air carrying hosepipe 41, whose opposite extremity is connected with an elbow-shaped pipe42 connected with the air feed, as hereinafter explained.

ach elbow-shaped pipe 40 is connected wi h its corresponding wood member39 by means of a staple'43 or other suitable fastening device.

As illustrated in the dra-wlng, (see vFig.

'2), each spring is'composed-of two parts,

but, as this feature is not vital to the mechanism, itis- 'not thoughtnecessary to give these parts separate reference characters I Mounted onthe framework of the machine, directly below the forward extremities ofthe springs 38, is a transversely-arranged pipe 44,having perforations45 on its upper side adapted to deliver jets of air .under pressure to.the lower surface of the cushion, while the latter is passing betweenthe springs 38 and while the opposite side edges of the cushion arebeing acted upon by the air jets from the elbow-shaped pipes .40. .Thistransverse pipe 44 is connected with the main air feed, as hereinaftermore .55

I sides of the housing 12',' as shown at 46, are 1 twoforwardlyextending. arms 47 whose fully-explained.

Pivotally connected 7 with the; opposite forward extremities are ntinwardly, as shown at 48, the outer extremities of two transverse bars52 being connected with the forward extremities of these arms, as.shown' at 50. .These bars 52 at their adjacentzextremities areconnected by two overlapplng curved metal bands 53, the saidba'nds beingand consequent l equipped with registering slots 54, through which ispassed a fasteningbolt 55, to the threaded end of which is applied a nut56, carrying a hand piece 57, to facilitate manual adjustment. Theextremities of these curved overlapping metal straps. 53 are secured totheir respective bars 52, as shown at 58. By virtue of this connection,the two bars may be thrown into the shape of an arch by raisingtheirinner extremities above their outerextremities, as best illustratedin Fig. 6. They may, however, if desired, be

dropped to the horizontal position, or even deflected downwardly orthrown to a position the reverse ofthe arch-shaped arrangement, shown inFig. 6.

To the bars 52 are secured blast pipes 59 and suction pipes 60, thesepipes 59 and 60 being connected withthe bars 52 by metal straps 61, oneextremity of each strap being secured to its corresponding bar 52, as

shown at 62, while the air blast pipes 59 are secured to the straps 61,as shown at 63, the

suction pipes being secured to. the forward upon the cushion as thelatter is passing ,un-

derneath the said pipes, while the suction pipes 60 are open, as shownat 68, directly in front of the air jets .67, whereby the dust,

which is removed from the cushion by the air jets-67, is drawn into thesuction pipes 60 by the suction 'incident' to the partial These fingersserve as vacuum produced inthe pipe 60 in a manner I hereinafterexplained Each suction pipe 60 is equipped with aforwardly and up-,

wardly extending branch pipe or nozzle 69, which is connected by meansof a flexible hose pipe 7 Owith a branch 71 of a Y-shaped fixture 72,whose junction end- .73 is con- I mated with a short pipe 74 leading toa'rel at-ively, small chamber. 75 into which pro- I trudes from below arelatively small air pipe 76, throughwhich air is deliveredunderpressure. into the chamber 75 and past the inlet end of the shortpipe 74, whereby suction is produced 'within the chamber iwithin thesuction pipes 60.

extremity with an outlet pipe '77, which leads to avertically-disposed"pipe 78 passing upwardlyfinto a sort of stack 79mount- The chamber 7 5"is connected at its upper I ed on the forwardextremity of the housing. The discharge of the air into the pttttlkqthrough the pipe 78 produces a partial vacuum within the stack, andtheresulting suction has a tendency to remove any dust which mightotherwise accumulate within the chamber inclosed by the housing 12.-

At-t'ention is called to the fact that-the bars 52 are so connected withthe forward extremities of the arms 47 as to permit the; movementrequired inadjusting the bar members by means of the curved overlappingbands 53. H

On the opposite sides of the framework are formed vertically slottedmembers constituting yokes 80, through which pass short air pipes Blconnected at'their inner extremities with double elbow-shaped pipes 82,through which airis delivered to the pipes 59 from hose pipes 83.Theseyokes' 80 permitthe necessary vertical movement of-the pipes 81,during theadjustment of the bars 52 to conforinto the shape of the topof the cushion under treatment, as here-" tofore explained. Theelbow-shaped pipes "82 are connected, asshownat 84, with the lowerextremities of spiral springs 85,w'hose upper extremities are connectedwithrthe framework, as shown at 86. In this manner, the combined blastpipe and suction mechanism is yioldingly supported It may, how.- ever,be further supported by means of pins 8'? passed through the. yoltes 80just below I the short pipes Slavhen the air blast-pipe suctionmechanism has been properly adjusted to conform tothe requirements ofthe particular cushion or cushions under treatment.v

In order to control the suction within the pipes 60, each of these pipesis equipped at its outer extremity witha disk 88, which is connectedwith the; inner extremity of a screw stem 89, whose outer extremity islocated just within the-housing 12 and fashioned to receive a wrench, asshown at 90.

The Velocity of the. current may be in.- creased by diminishing the sizeof the opening 68, and this may be accomplished by moving the disk 88farther into the pipes from their outer extremities.

The necessary air for supplying the air pipe members, as heretoforeexplained, and for producing the suction within the suction pipes istaken from an air'feed pipe 91, provided with a valve 9:2. Above thisvalve, a branch pipe 93, equipped with a valve 94, leads to thetransversely-arranged per-0 rated pipe 14, heretofore described.

Above the connection 95, between the branch pipe 93 and the main pipe91,. a pipe 96 is connected with the feed pipe, as shown at 97 the pipe96 being equipped with a valve 98- and extending 'rearwardly, where itisconnected, as shown at 99,'with a vertically-disposed pipe 100, locatedon one side ofthe machine." upper estremityc 1 [Of this pipe 100 isconnectedflwith the elbow 42 on one side of themachine, with which cneofthe hose pipes 41 is: connected. 2' From tlie 'lower extremity of thepipe 100,21. pipe member 102 extends transversely across {the machinebelow the :cjonveyer, and' connects with the lower. extremityof.a;pipe-;103,,exe

Assuming that the. endles s. comey'er "is I traveling, so that, its, uper 'r'unais iioying forwardly or in the direction of arrow A in Fig. 2,the cushion 36 to'bet r eatedfi's placed upon the rear extremity of theupper run of the conveyer, the housing being open at the rear end of themachine, as shown at 110, The cushion is immediately carriedwithinfrange of the beater straps 32, which act upon the upper surfaceof the cushion to loosen the dust and dirt carried thereby. As soon asthe cushion leaves-the beater, it is brought into operative relationwith the air jets issuing-from the short pipes 40, which jets actuponthe opposite side edges of the cushion to loosen the dust; while, atthe same time, air jets from the perforated pipe 44 are delivered to thelower side of the cushion. As the'cushion engages the springs 38, thesaid springs readily yield outwardly and allow the cushion to passthrough, the

furnishing springs being sufficiently weak to not inter fere with theforward travel of the cushion upon the conveyer. After the cushionleaves the air jets from the pipes and 44', as just explained, it movesinto operative relation with the air blast pipes fitl' 'and the suctionpipes. 60, which serve in their combined relation to remove all ofthe-dirt loosened by the mechanism to which the cushion has been.zprev'iously subjected, the said dirt passin "into the suction pipe andthence throug the branch pipes 69 and the hose pipes 70 to the Y-shapedfitting and thence-to the chamber, in which the nee-I essary suctionis-produced' through the in-' .strumentality of the air jet pipe 76,whence the dirt is carried upwardly through, the

pipe :78 and the stack 79 and out of the machme.
